CM11/CM12 Firmware Repository

Hello
Given that no one has put this up anywhere legible for the whole community to have access to here it is.
If you are upgrading to CM12, you are required to upgrade your phones firmware. Most new ROMs will check for this firmware upgrade.
This can be found here
If you are downgrading to CM11 or CM11S basad ROMs they REQUIRE a downgrade or you will experience all sorts of issues.
This can be found here
Make sure you use your favorite custom recovery to flash these
Cheers

How to install?
Could you please tell how to proceed? Do I flash the firmware over the installed ROM and then do all the wipes and last flash the new ROM?

The simplest thing to do is to just download the latest CM12 nightly, flash it, wipe the phone(not internal storage)... And then install the LP ROM of your choice

Sorry, I forgot to say that I want to downgrade to CM11S or CM11.

That isn't the simplest solution, the simplest solution is to just flash the firmware zips that are available. Flashing the whole CM12 ROM is kinda like buying a new car because you ran out of fuel, instead of just buying the fuel.

If you want to downgrade to CM11 or CM11s I'm rather sure you don't need any, because they come with the firmware. If you want to install a custom ROM than you probably need to flash the firmware extra before you flash the ROM.

I take it all I have to do is flash both of these files from above and my 05Q nandroid and all should be brilliant.

The Most Wanted
most people missed out the firmware part .. here he provides

Can i use this for 05Q? I am getting battery issues .

I'm not sure I understand - if I'm on stock CM11S, can I not just flash the most recent CM12 nightlies? I have to update the firmware first?

The CM12 nightlies contain the firmware so there's no need to flash it if you're flashing CM12. If you're flashing another Lollipop ROM you do need to flash it though.

The CM12 firmware link posted in the OP is not the latest one...request OP to update accordingly.

what cm11s version of firmware is most stable and battery friendly for 4.4 roms?

HI Timmaaa,
Just a doubt, as you said we need to install modem and firmware before downgrading to CM11s,
I just want to know that in what sequence do we install firmware, modem and cm11 and when and
what do we need to wipe in recovery.
One more question do we need to unlock the bootloader and root once again.
Plz help me out
ThnX

Boot into TWRP, full wipe (system, data, cache, dalvik cache), flash firmware and modem, reboot back to recovery, flash CM11, reboot into ROM. You don't need to unlock your bootloader, that remains unlocked unless you specifically lock it again via fastboot. Each time you flash a new ROM you need to flash SuperSU again to get root, unless the ROM is pre-rooted.

I believe some custom roms require flashing that, but I just rooted and installed twrp.
If flashing SupermanRom, then you need to install no_verity_opt_encrypt before flashing ROM.

Not really. It was just required for kernels with non disabled encryption but eventually it was integrated into SuperSU and now with sources we have non encrypted kernels. And why before flashing the rom?

You don't need it anymore, as we have kernel sources and You can download any rom and it will be working without encryption.

If it's not a custom rom then yes you will need to flash no verity zip unless you plan to root in which you can flash supersu which includes no verity.

Try booting to bootloader and flash TWRP. Wipe system and data partitions (I'd recommend wiping the internal storage too), cache and dalvik cache. Reboot to bootloader, and try flashing stock from there. Tell me if this works.

Tried that didn't worked it says something like bootloader security downgrade then it says failed

Maybe the bootloader is updated with the OTA update that's why it isn't flashing

you will need to restore stock kernel and recovery if you want to flash stock firmware.

I did that but then I wasn't getting OTA the latest OTA update

Oh! Can you try downgrading to MM and following the official OTA to N? I did that and it worked for me. I was using a custom ROM, with quark kernel, and all i had to do is wipe everything, and I could flash MM. I then got the system update. I installed the update and there were no problems.

I haven't tried locking the bootloader, so I cannot help with that. Sorry! You said you were on Nougat before downgrading to MM? Did you flash gpt and bootloader files? Could you downgrade your bootloader too?

I was just curious because the custom ROM I was talking about was built on CM 14.1, and I didn't flash the soak test before flashing the custom ROM. I could flash the MM stock firmware, including the bootloader, without problems. I was curious as to whether the custom ROM upgraded the bootloader or not. I guess it did not. Anyway, after the system update, I think my bootloader has been upgraded.

Way past that now. I've updated using the system update, so my bootloader is also upgraded. I've already taken a backup of stock nougat immediately after the update, so I won't be needing the MM stock anymore.

There is a stock nougat firmware which can be flashed by fastboot but after the latest update you can't relock your bootloader you have to wait for the latest firmware which is flashable through fastboot

you need to make clean install for this . it will surely work .
or you have to flash stock bootloader if havent made changes to system

AFAIK, the stock fastboot flashable firmware file available here has a bootloader that can be locked.

Does VBMETA have to be applied with each rom?

Or is doing this simply a one off if you are coming from a MIUI rom? I am technically adept and have been flashing roms for many years and things are always changing. So I just want to be sure.

Flash it only when you go to custom rom coming from miui stock rom, other than that you don't have to flash it or the vendor when you jump between the other custom roms

So it's kind of like a condom. :good: Thank you!

LOL

Why some custom roms don't need to flash VBMETA ? Even if coming from MIUI ?

you will most likely still need to flash vbmeta after updating your firmware manually.

Ok thx. This coming from MIUI. So I suppose that going back to MIUI' based rom, I need to reflash VBMETA.IMG, right? I take it in the rom ZIP of the MIUI rom, right?

ok to clear this up, vbmeta is only required when going from miui based roms to other custom roms. if u are going to flash a miui based rom, such as .eu, u do not require vbmeta. in fact, since u are going to flash a miui or miui based rom u might as well flash stock miui through fastboot, so there would be no confusion and no additional flashing.
when i was referring to updating firmware manually i meant flashing the firmware packages from xiaomifirmwareupdater.com rather than extracting from the miui recovery rom.

Not every custom rom. Don't need to flash vbmeta e.g. for thelazyindian's LOS, Syberia Project, AEX.

Do Xiaomi.eu roms have anti-rollback?

I wanna know xiaomi.eu roms have anti-rollback or not. Because I'm going to flash AOSP roms and even if I wanted to go back to MIUI, I'll only flash xiaomi.eu stables. So pls

As far as I know ARB is in the fastboot versions, there is ARB=0 in those ROMs, checked, If you have ARB>0 you'll not be able to flash by MiFlash. However you can flash by TWRP but only upgrade, downgrading in TWRP means you can brick in any time. Of course every single ROM flashing in TWRP require to disable Dm-Verity/ForceEncrypt, to avoid bootloops and problems with encryption after unlocking bootloader.
